bushnell radar

[Suf Daddy]

Describe the situation. Where (what environment) are you shooting it in? Indoors / outdoors / in car with defroster on?

I've noticed the Speedsteer updates fast enough that by the time the trigger is released another speed update has been displayed.

The Velocity are "C" cell batteries correct?

Any more pictures of the features / display ?

Does anyone elses Velocity display a speed for no reason. The fake speed goes away when you shooting a car.
I might just a bad unit.

It displays bogus speeds indoors, outdoors, inside the car. About 90% of the time, it displays the bogus speed. When you shoot a real target, the bogus speed goes away and the real speed displays. It uses two C batteries. It has a low battery warning below the KPH. The batteries are good in my velocity too (I checked w/ a volt meter).

The only thing I didn't check is maybe it uses high current that alkalines cannot provide. I have to try NICD batteries.

[joop1987]

If anyone has this gun and has a problem, switch to rechargable batteries (NiCD or NIMH) and the bogus speed problem will go away. Several places sell AA to C size adapters so you can use high capacity rechargable AA batteries in the gun. I do not have a C size battery charger so I use the adapters.


I am not sure why, but the Bushnell Velociy does not work well with alkaline batteries. If the alkaline batteries are brand new, you will get a couple of hours on them. Once the batteries get drained some (below 1.4V), the gun displays bogus speeds. The battery icon the the gun will NOT turn on when the alkaline batteries are below operating condition. From what I read, alkaline batteries do not work well with high current devices (digital cameras). If you use them in high current devices, the capacity of the battery goes down fast.

Once I put NiCd batteries in, the gun works perfectly.
Here are the readings I took from my gun:

Alkaline: Standby Voltage=2.94V, trigger Voltage=2.79V, trigger Amperage=360mA
NiCD Standby Voltage=2.75V, trigger Voltage=2.70V, trigger Amperage=280mA

The gun sometimes makes a high pitch buzz noise when bad alkaline's are used.

The bushnell claims on the box that it can get a reading from 1500 feet. Im doubt that, 1500 feet is close to 1/3 of a mile. Ive noticed since its a stationary radar and if your driving with it, I think it displays your speed. When shooting at a car while moving it displays that cars speed, then i think it add both your car and that speed together. I was driving in a 40PSL zone, going 45, I shot at a car, hit a 47 mph reading then still holding it it said 92 mph, then back to other cars speed. Me and buddy did a test with it near his neighborhood. He stood about 500 feet away from my car I turned a corner and he got my speed from about 500 feet away. I was going 55 and the gun read 55 he said. So its pretty accurate as well.

It is not a bougus claim i have triped my bushnell before and it trips consistently on my x-50 1/3 of a mile. And sometimes with v1 i get 1/4 a mile if im lucky. So yes it is transmitting this far. Weather u can get a speed this far away is a tottaly different story though..

I dont mean to bump ops: but can those bushnell speedster 2 guns measure a car etc going away from you as well?

You are incorrect. The 47 MPH reading you got was YOUR car. It can be a few MPH off depending on how you are aiming it. I have found that aiming it directly down at the road in front of you will provide the most accurate reading of your own speed. The 92 MPH reading you received was the ONLY point at which the gun was even registering the other vehicle you were attempting to clock. The reasoning behind this is simple. These guns are meant for stationary use to shoot baseballs and such. Therefore, they have no idea if they are moving or not. When you are shooting at oncoming cars, you have to get the angle JUST right and the 92 MPH reading you got was your speed added to the other vehicle's speed. These guns simply have no way of knowing how fast the other vehicle is moving or that there are 2 vehicles moving at all. So when you are moving, there is no possible way for it to know ONLY the other vehicle's speed.

It most certainly CAN.

It is actually a pretty good and accurate gun for the money. I have no problem clocking cars coming towards and going away from me. Pretty accurate gun overall. Using it while moving is another issue all together.

[corkguykev]

ok. 1 more question. do these radar guns come with a tuning fork?

I did an experiment with my Velocity 2.2 :

When I shoot at the air duct with no ventilation : no reading .

When I put the vent at lowest speed : reading 28 kms and the reading

change at each level , at full vent : reading 48 km

The radar is reading the fan speed , beat frequency .

Could the same principle be used in some form of jamming/interference ?

I know the echo of a car is much stronger than the beat produced by a fan , but can this introduce some clutter in the police radar ?

This phenomenon is described in Skollnik's Radar Book , it is called '' target induced micro-doppler '' .

MythBuster did a test with a squirrel cage installed on top of the car , I would have done it in front of the car , anyone ever tried this trick ?
